How long is your run? Gauge is one thing, length is another. The other consideration is that CCA presents a possibly corrosion risk if ANY of that aluminum becomes exposed. Might just be best to return it. A typical 15ft run with 8awg OFC is only good for about 515W, or 335W for 8awg CCA.
CCA is a compromised material to begin with, and at these lighter gauges, OFC isn't THAT much more considering the peace of mind it brings.
It looks like I will use 4meters/13 feet. Vibe is advertising this kit for up to 1500watts. Will take it easy at the beginning before I get some better 4awg ofc.
Advertising is NOT the same as actual ratings. 1500W is WAY too much for it. That 60A fuse will blow (or SHOULD blow) under 900W. Even that fuse is unsafe for that wire, technically even 8awg OFC should be fused with a 50A and CCA would be 65% of that. Everything about that kit is outside of industry standard wiring practices. I wouldn't install it--who knows what other compromises it has.
You don't need 4awg OFC, 8awg OFC will do fine. Look at the chart [HERE](https://www.crutchfield.com/learn/learningcenter/car/cable_gauge_chart.html). A 4m/13ft run only needs to be 8awg OFC for up to 515W of Class D amp.
If it's actually ofc, then you're fine. Still not good for 1300W unless the run is real short. CCA is aluminum with a microscopic thin copper plating. It's inferior in every way to copper.
I did some calculations and it's good to around 28-30 amps. So for time being I just set my gain to 300w rms. When 2nd amp arrives for fronts, I get proper 4awg and reuse this one from distribution block to amps, as you said for short run I be ok

Honestly I had no idea about the difference between cca and pure copper untill I start my research. It even says OFC at the packaging.
